I LOVE Brummel and Brown yogurt butter! yes yogurt!
It seriously tastes just like butter, it even has that slight hint of saltiness! It has half the fat of margarine or butter and is a little bit better for you over all, I love it. Plus you can spread it.

NOOOO
Sorry - You didn't ask which is healthy, then the answer would be neither. You asked which is healthier, ergo, the one with saturated fat but no trans fat wins. There is nothing wrong with a small amount of butter on toast, whole wheat pancakes, whatever.
